Building Energy Efficiency Rating CertificationBuilding Energy Efficiency Rating Certification
B.E.E.R.C program is for new buildings (since 2006)
- (2006~) residential buildings
- (2010~) office buildings
- (2013~) all kinds of buildings
Voluntary, but mandatory to public buildings
Range of assessment
- Heating energy consumption - Cooling energy consumption - Hot-water energy consumption - Lighting energy consumption - Ventilation energy consumption
